To all 'whom it corno/ern.'

Be it knownA lthat I, EDWARD KALLEN- BACH, a citizen of theUnitedStates, `residing in"Philadelphia, Pennsylvania, haveinventedcertain `lmprovem ents in `llillin'g- Machines, of Whichkthe followingis a speciiication.

@ne object of Vmy invention is to provide a novel andrelatively'simpleas `Well as substantial device foi" filling bottlesjorother containers with predetermined numbers of pills, tablets orVsimilar objects, the invenpage of the carrier after xthe feedingmechanism has ceased to acti Another object of the invention is toprovide novel means for supporting and presenting empty bottles to ypillfeeding device designed to periodically deliver predetermined numbers ofpills.

`These objects and other advantageous ends l secure as hereinafter setforth, ref- 'erencebeing had to the accompanying draW-v ings inV which:Figuresyl and 2 are respeictively a side elevation partly `in sectionand plan of a i'illing machine constructed raccording to my inventionFig. 3 islan end elevation ofthe machine shown in Figs. 1 and 2.

Fig. 4 is a vertical section on the line a-a Fig. 1;

`Fig. 5 iis a perspective view illustrating certain of the `mechanismconstituting my invention, and "flFiglgG is a fragmentary elevation of aAportion of my invention.

V`lin the abovedrawings 1 represents a suitable "base or supportingstructure upon "Which is mounted yan elevated reservoir for thereception of pills or other objects which it 'desired to feed ntobottlesor contain ers, this being mounted on the plate or platform 3 carried onfourlegs `or columns A4; .The container 2 Which is substantiallysemicylindrical in form has a fiatvertical y `a l n side which has along horizontal openm O extending for practically its entirey lengthimmediately above the platform 3 and partlyclosed by a verticallyslidable door 5. This latter is slotted at its loWer edge to permit ofthe passage ofa feeding' or measuring disk 6, being slidable in"suitable guideways parallel With the fiat facew of the container andheld in any desired position by a clamping bolt 8. rlhis latter isslidable in a vertical slot `formed in the front yside 7 of thecontainer andhas a clamping nut 9 whereby it may be tightened to holdthe door in any adjusted position. The measuring disk 6 is removably.fastened by a screvv` l0 to a rotaryplate 11 Whose top surface issubstantially Hush With the bottom ofthe container 2 and is operativelyconnected to ,said disk by a projecting pin 12 designed to fit into ahole therein. The plate "11 has its lower face provided with inclinedradial teeth 13 sothat itconstitutes in eiiect a beveled gear Which isrotatable on suitable spindle 14 carried by a transversely extending bar15 supported at its ends from the `underside of the platform 3.

For rotating this gear and plate Iprovide an electric motor 16 mountedon the base 1 and having its armature shaft connected through a belt 17With a pulley 18fix`ed to a shaft 19 carried by bearings .20L `Alsofixed to this shaft is a pinion 21 meshing With a gear 2 2 fixed to ashaft 23 on Which is also fixed a beveled pinion 24 engaging the gear13.

The tivo columns or legs 4 at the front end of the machine are connectedby a pair ofhorizontal bars or braces 26 and 27, to the first of whichis pivoted a lever 28 Whose upper end extends adjacent the beveled gear13 so as tobe periodically engaged by aprojecting pin or 25 thereon assaid gear is turned. The lovverend of this lever is connected through alink 29 With a reciprocable bar 80 operative in a Way provided by thecross bar 27' and a pair of E shaped. guides 31, there being a spring neexi-,ending between said here@ `and portion ofthe frame whereby the baris normally held at one extremity of its path of movement. Y

In order to prevent noise and jarring action, the end of the bar 30farthest from the spring has iixed to it a resilient or other suitableform of stop which by engaging one of the legs 4 serves to limit andcheck its movement under the action of the spring. Mounted upon the basein front of the container 2 is a standard or bracket 34 in which Aisrotatably mounted a spindle 35 having `formed in the cross bar 27, asshown in 25V Fig. 6. This arm 40, adjacent the ratchet wheel 38, carriesa spring pressed pawl 42 in engagement with the teeth of said wheel, andits outer extremity has a lug or projection 43 capable of engagingeither of two 30- pins 44 or 45 projecting horizontally through the slot41 for the reciprocable bar 30. The cross bar 27 is also provided with apair of horizontally projecting pins 46 designed to limit the anglethrough which the arm 40 may oscillate, their position being such thatthey will be engaged by the vertical projection 43 of said arm at theextremities of its swing.

The measuring disk 6 consists of a circular plate of wood or othersuitable material having a predetermined number of perforations or holesall at the same distance from its center and arranged at the samedistance apart, although they are omitted from a certain deiinite arc ofthe circle on which they are formed. In the platform 3 is mounted adownwardly extending tube 47 having its upper end flush with the topsurface thereof and its center line at the same distance from the centerof revolution of the plate 6 as are the holes 48 therein, so that as thelatter pass over the upper end of said tube their contents willnaturally fall therein under the action of gravity.

Slidably mounted on this tube is a bottle engaging cap 61 having apassage therethrough whose lower end is downwardly flared so that itwill receive and it down over the tops of the bottles or containerscarried by the ring 37. This cap is provided with a pair of oppositelyprojecting lugs or trunnions 49 resting upon and supported by the prongsof a fork 50 fixed to a horizontal spindle 51 mounted in a suitablebearin 52 on the under side of the platform 3, lso

fixed to thisv spindle is a curved arm 53 placed to be engaged and movedby a pin 54 projecting from the upper end of the lever 28.

The brake drum 39 on the spindle 35 is engaged by a brake band 54 one ofwhose ends is permanently attached by a screw 55 to a post 56 projectingupwardly from the base 1, while its second end has connected to it ascrew 57 whose end passes through a lug 58 on the top of said post andis provided with a nut whereby the band may e tightened on the drum asdesired.

Under conditions of operation the container 2 is filled with pills orother material which it is desired to feed into bottles placed in theholes 60 of the ring 37 and current is supplied to the motor 16 whichthrough the belt 17, pulley 18, gears 21, 22, and 24 drives the beveledgear 13 and the plate 11 which in this instance is integral therewith.The consequent rotation of the feeding disk 6 beneath the mass of pillsin the container allows one or more of the latter to enter each of theholes 48, depending upon the thickness of said plate andupon the size ofthe pills, and the various parts are so proportioned that during thetime that the holes 48 of the plate 6 are being passed over the upperend of the tube 47, the cap 61 rests upon the top of a bottle in one ofthe holes 60 of the ring 37. As a consequence the pills carried by theholes of the disk 6 are successively discharged through the tube 47 intosaid bottle.

Immediately after the last of the holes 48 has discharged into the tube,the pin 25 engages the upper end of the lever 28 and swings it on itspivot so that its horizontal projecting pin 54, moving in engagementwith the arm 53, turns the spindle 51 and swings upwardly the fork 50,thereby lifting the cap 61- out of engagement with the lled bottle. Atthe same time the lever 28 moves the bar 30 in its guides until its pin45 comes into engagement with the vertical pin 43 of the arm 40, whichthrough its pawl 42 turns the ratchet wheel 38, and with it the circularplate 36 and ring 37. Such turning continues until the pin 25 passes outof engagement with the upper end of the lever 28, which, with the bar30, returns to its normal position under the action of the spring 32.

Y This forward swingof the arm 40 is suiiicient to move the ring 37through the angular distance between two adjacent holes 60, all ofwhich, as before noted have been reviously lilled with bottles, so thatw en movement of the ring ceases, an empty bottle is imediately underthe cap 61 while the filled bottle is removed by the operator. The cap61 is lowered over this empty bottle upon the movement of the bar 30 toits normal position, since the pin 54 moves under the arm 53 to such aposition as will canse the fork 50 to lower said cap. This lattermovement of the bar 30 does not aii'ect the arm 40 until the pin 43 ofthe latter is struck by the horizontal pin 44, whereupon said arm islikewise carried to its normal position in which said pin 43 restsagainst the stop pin 46.

At the end of the forward swing of the arm 40, the momentum of the ring37 and its attached parts would naturally tend to cause it to continueturning through a greater or less angle but by adjusting the brake band54 by the nut on the screw 57, said ring is held by the drum 39 so thatits movement ceases as soon as the pawl 42 stops its forward movement.Moreover said brake band and drum serve to hold the ring 37 and itsattached parts from any possible backward movement during the time thatthe pawl 42 is being moved over the teeth ot' the ratchet wheel 3S bythe arm 40, so that the ring 37 is always stopped with an empty bottleunder the cap Gl. Shortly after the cessation of movement of the bottlecarrying ring, the continuously rotated feed plate 6 delivers anotherseries of pills to the tube 47 thus lling a second bottle in the samemanner as previously described, it being noted that this movement of thering 37 to replace a filled bottle by an empty one in line with the tube47 occurs while the unperforated space of the feed plate 6 is beingmoved over said tube and while the bottle engaging cap is raised.
